A displacement diagram is a graphical representation of the relationship between the different variables involved in a cam mechanism, such as the position of the cam, the position of the follower, and the forces acting on the cam and follower. It is a useful tool for understanding the operation of cams and their effect on the system.
The displacement diagram consists of two sets of coordinates: the crank angle and the follower angle. The crank angle represents the angle that the crank has rotated since the start of the stroke, while the follower angle represents the angle that the follower has rotated since the start of the stroke.
The displacement diagram can be used to analyze the following relationships:
Angular displacement: The angular displacement between the crank and the follower is equal to the displacement of the follower.
Linear displacement: The linear displacement between the crank and the follower is equal to the product of the angular displacement and the radius of the cam.
Force and torque: The force and torque acting on the cam and follower are equal to the negative of the slope of the displacement curve.
The displacement diagram is a powerful tool for understanding the operation of cams and their effect on the system. It can be used to analyze the relationships between the different variables involved in a cam mechanism and to design and select cams for specific applications
